What the rule says
Florida's constitutional homestead protection extends beyond the devise restrictions covered in SB4 (Art. X § 4) to include property tax benefits under Article VII § 4 of the Florida Constitution. Two key features:
Save Our Homes assessment cap
Under the Save Our Homes amendment (passed in 1992 and codified in Fla. Const. Art. VII § 4(d) and Fla. Stat. § 193.155), the assessed value of a Florida homestead can increase by no more than the lesser of: - 3% per year, or - The percentage change in the Consumer Price Index for the prior year
The cap applies as long as the property remains the homestead of the same owner. When a new owner acquires the property (whether by sale, gift, or inheritance), the assessment generally resets to the property's full market value, and the new owner's ownership starts a new Save Our Homes calculation.
Over time, the Save Our Homes cap can produce a significant differential between assessed value and market value. A homestead purchased in 2000 for $200,000 may have a market value in 2026 of $750,000 but an assessed value of only $300,000 — the differential reflecting the years of capped 3% annual increases against actual market appreciation.
This differential is sometimes called the "Save Our Homes savings" or the "assessment differential."
Homestead portability
Under Fla. Const. Art. VII § 4(d)(8), and codified in Fla. Stat. § 193.155(8), a Florida homeowner who establishes a new Florida homestead can transfer ("port") accumulated Save Our Homes assessment differential to the new homestead. The portability rules provide:
- Up to $500,000 of accumulated assessment differential can be transferred from the prior homestead to the new homestead - The new homestead must be established within 3 years after the prior homestead was abandoned - The portability adjustment reduces the new homestead's assessed value by the ported differential, capped at $500,000 - The new homestead retains the cap-protection going forward (3% annual increase limit)
The portability rule is one of the most distinctive features of Florida property tax law. It allows long-time Florida residents who upgrade or relocate within Florida to preserve significant tax benefits accumulated over years of ownership.
What this means in practice
The combined Save Our Homes + portability framework produces several consequences:
- Long-time Florida homestead owners enjoy substantial property tax savings as their assessed values lag market values by years of accumulated 3%-cap protection. - Inherited Florida homesteads typically reset to market value for new owners. The new owner generally cannot inherit the lower assessed value (subject to specific exceptions for homestead transfers within families that meet the constitutional requirements). - Selling and rebuying within Florida preserves accumulated benefits up to the $500,000 portability cap. A Florida homeowner who sells a long-held home and buys a new one within 3 years carries forward up to $500,000 of Save Our Homes savings. - Selling and not rebuying within 3 years loses the accumulated benefits. The 3-year window is firm.
For Florida estate planning, the framework has meaningful implications:
- Inherited primary residences face full property tax reassessment. Heirs who move into an inherited Florida homestead generally pay property tax based on current market value, not the decedent's assessed value. - Lifetime transfers between Florida residents may preserve some benefits. Specific homestead transfer rules can preserve the assessment cap in narrow circumstances, particularly for transfers between spouses or to certain family members. - Coordinating with constitutional homestead devise restrictions. The devise restrictions in Fla. Const. art. X § 4(c) (covered in SB4) operate independently of the property tax framework. Homestead can be inherited subject to the devise restrictions, but the property tax assessment usually resets at the inheritance.
Coordination with other Florida tax features
Florida's lack of state income tax and lack of state estate tax (covered in fl_no_state_estate_tax_snowbird_domicile_traps) operate alongside the homestead property tax framework. Together, these features make Florida among the most tax-favorable states for residents, particularly for retirees and high-net-worth individuals.
Key interactions: - Homestead exemption from forced sale (covered separately in SB1+SB4) protects against creditors during life. - Constitutional homestead devise restrictions restrict who can inherit the homestead. - Save Our Homes assessment cap limits property tax growth during ownership. - Homestead portability preserves accumulated benefits when relocating within Florida. - No state estate tax means estates pay no state-level death tax.
For lifelong Florida residents, the combined benefits can save tens of thousands or hundreds of thousands of dollars over a lifetime compared to similar wealth in higher-tax states.
Procedural requirements
Claiming Save Our Homes and portability requires affirmative action:
- Homestead exemption application. A homeowner claims the homestead exemption by filing with the county property appraiser by March 1 of the year for which the exemption is claimed. - Homestead designation triggers Save Our Homes. The Save Our Homes cap applies automatically once homestead status is established. - Portability requires filing. When establishing a new homestead, the owner must file Form DR-501T (Transfer of Homestead Assessment Difference) with the county property appraiser to claim portability of accumulated differential from the prior homestead. - Documentation of the prior homestead's differential. The portability application requires showing the assessed value differential at the time the prior homestead was abandoned.
Failure to file the appropriate forms within deadlines forfeits the exemption or portability for that tax year.
What you can do about it
For Florida homeowners:
- Establish homestead status promptly. File the homestead exemption application by March 1 to qualify for that year. - Maintain homestead status. The Save Our Homes cap applies only while the property remains the owner's homestead. Renting out the property, abandoning it as the primary residence, or other changes can terminate the cap. - When relocating within Florida, file portability promptly. The 3-year window from prior homestead abandonment is firm. Filing the transfer form is essential. - Coordinate with estate planning. Inherited homesteads typically reset; planning may anticipate this.
For heirs of Florida homesteads:
- Expect property tax reassessment. The heir's new assessed value generally equals the property's market value at acquisition. - File for homestead exemption if establishing residence. Establishing the inherited property as the heir's homestead allows Save Our Homes cap to apply going forward (from the new market-value baseline). - Plan for the property tax increase. The annual property tax may increase substantially compared to what the decedent paid.
Who this affects most
Florida's homestead property tax framework is most consequential for:
- Long-time Florida homestead owners enjoying significant accumulated Save Our Homes savings - Florida residents relocating within the state who can preserve up to $500,000 of accumulated differential - Heirs of Florida homesteads who face reassessment to market value - Florida estate planners coordinating homestead protections with overall planning - Retirees and others choosing Florida residency for tax efficiency
The Save Our Homes + portability framework is one of Florida's most valuable resident benefits. Combined with no state income tax and no state estate tax, the homestead framework substantially reduces lifetime tax burden for Florida residents who establish and maintain homestead status properly.
